BOX-CAR DOOR.

. Specification of Letters latent.

To all whom it may concern:

Be it known that I, Wroo G. NYMON, a citizen of the United States,residing at- Argusville, inthe county of Cass, State of North Dakota,have invented certain new and useful Improvements in'Box-Car Doors; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. I

This invention relates to new and useful improvements in grain car doorsand is particularly directed to the provision of a wicket or reliefdoor.

A further object of the invention resides in the provision of such agate which will prevent the leakage of grain from a car to which my gateis applied.

Other ob ects and advantages, such as ease of operation, simplicity,durability in service, and cheapness in manufacture together with thegeneral improvement of the art will become apparent during the course ofthe following description.

Reference is had to the accompanying drawings wherein similar charactersof reference designate corresponding parts throughout the several views,and in which:

Figure 1 is a side elevation of a grain car door having associatedtherewith the improved wicket or relief gate; Fig. 2 is a verticalsectional view through the relief gate.

Referring now more particularly to the accompanying drawings, 10 and 11designate respectively the upper and lower sections of a grain car doorprovided at their ends with suitable members 12 for tightly closing thespace between the edges of the door and the door frame, said membersbeing actuated by suitable levers 13. Secured on the bottom edge of thedoor is a T-beam 17 which seats in a suitable channel 16 formed in thebottom of the door frame.

The T-beam 17 is preferably formed with an upstanding flange 17 againstwhich the lower edge portion of the vertically slidable wicket or reliefgate 27 is seated, and this gate is preferably of sheet metal and isslidable within suitable guides or gibs 28 it being understood that thedoor section 11 between the gibs 28 is cutaway. A bracket 29 is securedat the lower edge of the gate and caries a pivot or bolt 30 whichextends Patented July 21, 1914, Application filed May 28, 1913. SerialNo. 770,457.

the latter being provided with a stud 33,

and having an'aperture in its upper end. A vertically disposed bar- 3 1is provided with a series of teeth 35' and notches 36, and the upper endof this bar is secured to the upper portion of the gateway which isclosedby the gate 27, while the lower portion thereof is secured to theT-beam 17. Abracket 37 is secured to the door member 11 adjacent to-the'ateway, and this bracket member is provided with an aperture whichregisters with the aperturethrough the lever 32 when the gate is in itslowermost position, so that a locking boltor other suitable sealing orsecuring member 38 may be passed through the registering apertures forsecurely locking said gate in its closed posi tion.

In operation, assuming the car to be filled with grain which is to beunloaded, the operator first releases the upper end of the lever 32 fromthe bracket 37 and swings said lever downward, so that the stud 33engages in the lowermost notch 36 and presses the gate upward a shortdistance. The lever is now pulled longitudinally, so that there isrelative movement of the element 30 and the slot 31, thus allowing thestud 33 to be disengaged from the lower notch and engaged with the nexthigher notch, and the lever is again swung downward, so that, byrepeatedly thus operating the lever 32, the gate is raised by degreeagainst the pressure and consequent friction of the grain, which latternow flows through the gate into whatever receptacle has been providedtherefor.

It is obvious that by reversing the action of the lever 32 as justdescribed, the gate may be closed after a suitable quantity of grain hasbeen withdrawn, so that when one vehicle has been filled, said gatemaybe closed while another vehicle or receptacle is being placed for thereception of the grain.

From the foregoing, it will be seen that I have provided a car door ofthis character which is fully capable of attaining the foregoingobjects, in a thoroughly practical and effective manner.

I do not limit my invention to the exact details of construction,combination and arrangement of parts, as herewith illustrated anddescribed, but my invention may only. be limited by a reasonableinterpretation of the claims. ii l I claim: 1. In a car door having agateway therethrough, a gate slidably mounted over the.

gateway, a notched bar disposed vertically within the gateway, a bracketa djacentto mounted notched bar, a bracket adjacent to i the gateway, abracket secured on the gate, a lever connected to the last said bracketand. adapted for longitudinalv and, pivotal movement relative theretoand adapted for engagement with. the first said bracket for holding, thegate closed, and means carried by the lever for engaging the notches ofsaid vertical bar and adapted to coact therewith for raising the gate.

3. The combination with a vertically slidable gate and a gateway, ofcombined lockmg and lifting mechanism comprising a :vertically disposedbar secured to the gateway and provided in its outeredge with horizontalnotches having their inner ends enlarged, a bracket adjacent the upperportion of the gateway, a bracket on the gate, a lever slidably pivotedto the second bracket and adapted for engagement with the first brackettohold the gate closed and a, lateral extension on the, pivoted endportion of the. lever adapted to engage in the notches whereby rockingmovement of the lever will lift the gate.

I 1. testimony whereof, I a'lfix my signa: ture, in the presence of twowitnesses.
